Abstract
Voltage resistance insulation testing device, the circuit including shell and its inside, circuit are at least one three-prong plug, and the firewire L of each three-prong plug is connected with zero curve N and drawn jointly as power input, and the ground wire E of each three-prong plug is drawn jointly as ground terminal.The utility model provides a kind of voltage resistance insulation testing device, which tests for electronic equipments safety, voltage-withstand test and Insulation test, it is therefore an objective to investigate the insulation performance between equipment under test power input (L, N) and shell or ground connection.After the device, test end in contact is good, tests handy and safe, and the device jack is more, can measure multiple devices simultaneously.
Description
Technical field
The utility model belongs to test device field, and in particular to a kind of voltage resistance insulation testing device.
Background technique
In existing measurement means, measurement is clamped to the mains terminals period of the day from 11 p.m. to 1 a.m of equipment under test, needs to measure firewire respectively
And zero curve, often bad because contacting, measurement folder can slip, and careless slightly, in fact it could happen that two electric pole short circuits or Danger Electric shock risk exist
Security risk.Meanwhile the presence of instrument test electrode is equal to the creepage distance and electric clearance for reducing equipment under test, does not meet
Standard requirements.
Summary of the invention
In view of the above-mentioned problems, the utility model provides a kind of voltage resistance insulation testing device.
To solve the above problems, the technical solution adopted in the utility model are as follows: voltage resistance insulation testing device, including shell and
Its internal circuit, circuit are at least one three-prong plug, and the firewire L of each three-prong plug, which is connected with zero curve N and drawn jointly, to be made
For power input, the ground wire E of each three-prong plug is drawn jointly as ground terminal.
The utility model provides a kind of voltage resistance insulation testing device, which tests for electronic equipments safety, pressure resistance
Test and Insulation test, it is therefore an objective to investigate the insulation performance between equipment under test power input (L, N) and shell or ground connection.It adopts
After the device, test end in contact is good, tests handy and safe, and the device jack is more, can measure multiple devices simultaneously.
Detailed description of the invention
Fig. 1 is schematic diagram；
Fig. 2 is test chart.
Wherein, 1, shell, 2, power input, 3, three-prong plug, 4, ground terminal, 5, three hole plugs, 6, equipment under test, 7,
Measuring instrument.
Specific embodiment
As described in Figure, voltage resistance insulation testing device, the circuit including shell 1 and its inside, circuit are at least one three core
The firewire L of plug 3, each three-prong plug 3 is connected with zero curve N and is drawn jointly as power input 2, the ground of each three-prong plug 3
Line E is drawn jointly as ground terminal 4.
The test electrode of measuring instrument 7 is clamped to the power input 2 of test device, another test electrode and equipment under test
6 shell or the ground terminal 4 of test device connect.
The test device is furnished with the proofreading equipment of a 300K Ω, because the leakage current very little of equipment under test 6, almost nil,
Ammeter pointer is almost motionless, in order to which whether validation instrument itself is intact with test device, powers on really to the application of equipment under test 6
Pressure first accesses the proofreading equipment of a 300K Ω between power input 2 and ground terminal 4, applies the voltage of 1500V before testing,
The electric current that 5mA can be generated can prove that test device is intact, can be safe to use, and also whether provable instrument shows accurate.School
To finishing, pulls the plug out of the socket and remove the proofreading equipment of 300K Ω.
By the corresponding three-prong plug 3 of three hole plugs, 5 insertion apparatus of equipment under test 6, apply the test voltage of standard requirements,
If test passes close measuring instrument there is no flashover or punch-through, three hole plugs 5 are extracted.
